To. all whom t may. concern.; l

Be it knownA that 1 HENRY E. Mormon?, a citizen of the Unitedv States ofAmerica, re,- siding at Muskegon Heights,l in. the county ofV Muskegonand State of Michigan, haa/Te inventedv certain new andl usefulImprovements` in rfool-Carrying ttachments for Metal-Working: Machines,of which the following is a specification, reference being had thereinto the accompanying drawings.l

This invention. relates to. tool carrying attachments for metalmachines' and more particularly to tool carrying heads of the charactershown and described in my United States Letters Patent numbered1,206,884, datedV December 5,A 1916.,

The object of the present invention .is to increase the efficiencyofheavy dutyl metal working machines by so constructing and` arranginganattachment as to make the same applicable tothe performance vofa widerange of work and adaptable to ed'ect tool adjustments for variouskinds. of' work;

A further objectis to provide an arrangement whereby a pluralityv of'tools is carriedl by a. single head, saidi head being quickly adjustableto bring any one of the tools into. operative position, andy said-toolsbeing independentlyV adjustable to thework. It is also anA object toprovide 'certaine other new andi useful features, intheconstruction andfcombination of parts, all as hereinafter more fully described,

lVithlthe above; and other ends i-I1-view,the invention consists inproviding a .head1 attachment for heavy duty metal working machines,whereby said' head' may be rota,- tivel'y adjustedj without detachmentofthe head from thema-chine and whereby the headj may be attached to ordetached from the ram of a shaper with, facility..

The invention further consists in certain other new and useful featuresand in other matters hereinafter set forth. andV more parn ticul'arlypointed out in the appended. claims, reference being had to theaccompanying drawings, in which y L Figure l is a side elevation of adevice illustrative of the invention and showing the-same as applied toa draw-cut Shaper;

v substantially upon the line 9&9 of Fig. 9..

VAs. illustrative of an application of the invention, in Fig. l of thedrawings, a portion'of adraw-cut shaper of an oldi and well" knownconstruction is shown, the frame ofthe Shaper being indicated? atA 1 andthe work holding bed' which is positioned' at the forward side of theframe is indicated at 2'.' The usual reciprocating ram 3" is' carried bytheframe and' entends horizontally above the bedV 2, said ram beingreciprocat- .ed. by the, usual drivej mechanism: (not shown), and;ybeing adapted to carry cutting tools uponV its` freel end' foroperating upon "'1` the workv which is secured in place upon thebed'below. Further .description of the drawcut shaper isdeemed"unnecessaryas it forms no part of thisA invention', thisinvention relating" particularly to 'ai tool carrying d`evice or head'adaptedY .tobe attached to the externallyV screw-.threaded forward endof the ram` of Shapers where the cutting tool is reciprocated by the ramrelative to the work or said* head maybe applied toother forms of heavy'duty metal working machines, such as planerswherein the work isreciprocatedt yrelativeV to the milling` tool.` or tools.

The tool carrying device' or head; illustrative of the presentinvention, comprises a circular drum 41 whichL is formed at its lowerside with a half bearing to engage the end' of theram, said half bearingbeing internally screw-threaded` to engage the screw-threads formed on`the endl of the ram. lVithin the druml is a detachable half bearing 6 toengage the upper side of the screwthreaded end of the rain, said" half'bearing beingl also internallyv screw-threaded", and this half bearingis detachably secured withlill) lll in the drum by means of stud bolts 7(see Fig. 4) on the drum at each side of the half bearlng 5 to engageopenings in ears 8 on the sides of the detachable half bearing 6, nutsbeing provided on the studs to engage the ears and force the movablehalf bearing into engagement with the ram and toward the half bearing onthe drum. rlhe half bearing 6 is further secured to the drum by. meansof bolts 9 carried by the drum and extending through vertical slots 10in an upwardly extending bracketporf tion 11 which is formed integralwith the half bearing 6 between the ears 8 thereon and is adapted toengage the front end wall 12 of the drum. The half bearings and 6 thusreceive the screw-threaded end of thev the end of the ram without thenecessity for screwing it in place by rotative movement of the drumrelative to the ram, the half bearing on the drum being simply engagedwith the end of the ram and then the movable half bearing moved downwardinto engagernentV with the ram to interlock the threads on the ram andbearing-parts, and then by tightening up the nuts on the studs 'l andbolts 9 the two halves of the bearing are clamped firmly about the endof the ram and the screw-threads'drawn into interlocking engagement tofirmly and rigidly hold the drum in place upon the ram and againstrotative movement relative thereto. Quick detachment of the drum fromthe ram is effected by loosening the nuts on the studs 7 and bolts 9,when the upper half of the bear-- ing may be moved upwardly asuliicientdistance to disengage the threads, and the drum slipped from the end ofthe ram. v

rllhe outer rim or circular wall 13 of the drum 4 is provided with anannular out* standing rib 14 and a suitable carrying frame or head 15,which is of circular outline to correspond with the circular formationof the drum, is provided with an outstanding annular end flange 16having an internal diameter corresponding with the external diameter ofthe drum 4 to lit over said drum, and the end Awall 17 of thissupporting frame or head is adapted to lie parallel with the face of thewall 12 of the drum, with the outer end of the flange 16 abutting therib 14 on the drum. To lock the supporting frame in place upon the drum,a split ring 18 is provided having an inwardly extending annular fla-nge19 to engage one side of the rib `14 and this ring is internallyscrew-threaded to engage the screw-threaded outer face of the flange 16.By turning the ring 18, the frame 15 is drawn toward the drum andtheflange 16 brought into firm frictional engagement with t-he rib 14, andthen by tightening the nuts 20 upon the ends of a clamping bolt 21 whichpasses through openings in lateral ears 22 adjacent the divided ends ofthe split ring 18, said ring is drawn into close frictional and clampingengagement with the flange 16 on the frame 15 and with the drum 4. Thesupporting frame 15 being' thus mounted upon the cylindrical outersurface of the drum 4, may be rotated rela tive to the drum and ram 3 byloosening the bolt 21- and opening the split ring 18 slightly so thatthe frame and ring will turn freely upon the drum. The supporting frame15 which carries the cutting tools as.Y hereinafter described, maytherefore beerotated upon the drum 4 to bring Yanyy one ofthe cuttingtools into operative position and this adjustment may be quicklyeffected, thus facilitating the operation of changing tools to perform aseries of different operations upon the work, these several tools beingset up in the head to perform the several operations upon the work inhand, and retaining their setting so that itis unnecessary to reset thetools for each operation upon each piece of work when a large num ber ofpieces are to be machined in a like manner.

In the frame member or supporting head 15, is provided a transverselslot or guide way 23 extending transversely of the head near the lowerside thereof and in this slot two blocks 24- are mounted to slidetherein, and secured to each block is a supporting plate or member 25Yhaving a plane outer face against which the inner face of a sup portingplate 26 engages, said platesv25 and 26 being detachably and adjustablysecured together by a bolt 27 passing through an opening inthe plate 25and through an elongated slot 28 in the' plate 26 located in an upwardextension of the plate. `A clapper box 29 which is of rectangular formin crosssection is sleeved upon an outwardly projecting stud on theouter face of the plate 26,.said stud being of rectangular form incross-section to fit within the opening of the clapper box, which box ispivotally attached to the stud by a pin 81 passing through openings inthe sides of the box and through an opening inthe stud near the upperand outer corners of the box.

The plate 25 is detachably secured to the block 24 and the plate 26wit-h its stud 3 is secured to the plate 25, by means of a bolt 32extending through openings in the block plates and stud and is providedwith a head 33 (shown in dotted lines in Fig. 4) at its inner end toengage a recess in the back of the block 24 and with a nut 84 on itsouter end to engage the outer side of a plate 34 which is held by thenut Vand bolt firmly against the end of the stud 30 with the edges ofsaid plate overlapping the end of lOU' CII

the clapper box to limitthe swinging movement of' the box in onexdirection. The bolt' 32 thereforel forms means for securing' the Vplate25 to the blocfk 24 and also for pivotally secu-ring the supportingplate 26 to the plate 25'. The lower side of the stud 30 is relieved orcut within the clapper boX to permit of aslight swing; ing movementv ofth-ey cflapper box upon the stud about its pivot 3l andin eachside ofthis clapper box is formed a groove or channel 3-5 to receive a cuttingtool 361, said tool being of rectangular forinin crosssection` andfitting within either groove, and to hold the tool in place in itsgroove, set screws 37 are provided to engage the ,forward edge of thetool and securely clamp it within its groove or channel in the side ol?the clapper bon. To normally 'ho-ld the clappe-r box turned upon itsIpivot and in a. vertical position, a; flat leafspring 38 is provided,said spring being secured to the lower side of the stud 30 within the`space formed by cutting away this lower side of thel stud and the freeend of this spring is arranged; to ri'd'e upon the inner face of thelower Wall of the cla-pper 'bex to exert a pressure thereon for swingingthe box upon its pivot. The tool 36 may be placed in the groove orchannel eitl'ier side of either clappe-r' box, and as Vthese cla )perboxes Lare each carried by a separate slide comprising the block 24 andplate 25, which slides are movable transversely ofthe head Within theguide ways 23, said clappe-r boxes may be moved toward or from eachother to adjustA the tools relativelyT and relative to Ythe verticalcenterline of the head. When it is desired to bring the tools closetogether, they may be removed from the holding grooves in the outersides of the clapper boxes to the grooves in the inner sides thereof andtoo-ls of a. suitable form provided to perform a particu-lar operation,such as cutting a deep narrow groove or facing the bottom and side wallsof such a groove. Then the tools are set for facing the side walls of avgroove, it is necessary, .in order to provide a clearance, that thesetools be set at a slight inward incline toward each other and thissetting is accomplished by slaclrening the nuts on the bolts 2T andswinging the supports for the clapper boxes, comprising the plates 26and studs 30, upon the bolts 32 relative to the supporting plates 25. Ina like manner, the tools may be given a reverse slant when employed infacing the outer side faces of an upstanding rib or wall on the work orother parallel side faces which it is desirable to face olf. As the headis applied to the ram of a drawcut shaper, the Working stroke ishorizontal and inward or toward the frame lV of thr-l machine, and torelieve the drag of the tool upon the outward stroke o-f the rain, the

clappe-r boxe-sare piwetallv sup-ported, as previously described. V

1 To facilitate the accurate adjustment of the ytools toward and? from.leac'l'r. othen. riglit and left'- hand screws '35).' are .provided asshown inFig. 2 between theadjaeent stdes of the members 25 to space :theslides-:coni- 'prising said members and. their blocks 24,

apart andtlns aecurateilyl space Vthe tools carried thereby. Tliis'toolcarrying head is particularly adapted for use 'in machining 'largecastings, such as locomotive drive boxes, wl'iere it is'neeessary toErniisliiparallel surfaces, plane oil' horizontal.-'sin-'faces,` tinishthe sides andi 'bottoms .of grooves oiiffways, andperform number ofsimilar." operations upon the sam'epiireee ofworlr, as one or moresurtaeesmay be finished at the samer time and the tools quickly andeasily adjusted or changed to perform the. se-veralioperations. It isnecessary, however, in performing certain operations, to usel a vsingletool and in order` that a single tool may be .used without thenecessityfor removing; heentire head from the rana,and-substituting an;-V otherftherefor carrying 4 asingle tool, a third elapper box 402 is providedfor hold-ing a single -t'ool` with the tooll extending radially of theaXi-saof the headaidclaprper being pivotallysupperted adjacent onecorner thereof. upon .a f pivot pin 4l extending throughy :thebox and-th-rouglropenings in a pair of parallel ears 42 which are formedintegral with :the frame .or carrying member 15 adjacent. .the vsidethereofv opposite that 'at which the transe-vree Way 2i3'1is located,said ears extending outwardly Vfrom the outer side .of the frame... Thiselapper box has a .centralrectangular opening toreceive the tool 42.awhich is held in place thereinin any suitable manner, as by a set screw43 and to hol/d the clapper box turned upon its pivot into. engagementwith au abutment bar v44, a coiled spring145., Fig. 3, is set Within arecess in the frame l5 to bear against the inner sideedge of theclapperboX; The abutment bar 44 is. secured by belts 46 to the outer ends ofthe-.ears 42,

spanning .the space between the ea'rswithin which the clappe-r boxrotates, and thus the When it `'s desired to use a single tool Vinperforming a certain operation upon. the

work, it is unnecessary to remove the entire Vvhead from the ram. andsubstituteanother therefor carrying a single tool, as the single tool42a may be readily broughtA intoopera- 'tive position by rotating thecarrying frame i5, as previously described, upon the drum 4. By a propersetting of the rotatable carrying frame l5 relative to thedrum, the

lll?) tool may be given the desired lateral inclination to perform theWork Yin hand.

To accurately hold the frame in any one of the several positie-ns towhich it may be rotated to position the tools in the desired relationtothe Work, a plunger 47 (Fig. 8) is mounted in a bore 4S providedtherefo-r on the Wall 17 of the frame or carrying member 15 to projectthrough said Wall into engagement With a hushed socket 49 in the Wall 12of the drum 4, said plunger and socket being tapered to provide foraccurate location and firm holding of the frame' relative to the drum. Astem 50 is provided on the plunger, Which stem extends outwardly throughthe kbore With a coiled spring 51 sleeved thereon between the plungerand a cap member 52 closing the outer end of the bore, said `springexerting a force `to normally hold the plunger projected into itssocket, and said cap 52 is formed with a transverse il-notch 53 in itsouter face to receive a pin 54 carried by the stem` 50 and extendingtransversely thereof. By turning the stem by means of the handle 55 onits outer end, the ends of the pin 54 are caused to ride up the sides ofthe V-groove, thus moving the stem endWise against the action of thespring 51 and disengaging the plunger from its socket in the Wall 12,permitting free turning` movement of the carrying framey 15 relative tothe drum 4. Any desired'number of sockets 49 properly positioned in theWall 12 may be provided to provide for holding r the frame in theseveral positions for properly positioning the several toolsrelative tothe Work. i

To frictionally hold the frame 15 against easy turning relative to thedrum and also take up all possible lost motion, a friction disk 56 (Fig.9) is mounted in a recess in the falce of the Wall 17 to engage theopposed face of the Wall 12 and this disk is adapted to be forced intocontact With the Wall 12 by means of a screw 57 operated by a handle 58on its outer end.V

By providing a tool carrying head, of the character described,applicable to the ram of a draw-'cut shaper, a Wide range of ivo-rk maybe performed without the necessity for removing the head from the ramand substituting another therefor, and a quick and accurate adjustmentof the several tools is facilitated by the arrangement, as the desiredtool may be brought into operative position by a rotative movement ofthe head. Further, the application of the head to the ram and itsremoval therefrom 'is greatly facilitated by the employment of atwo-part threaded bearing to engage the screwthreaded end of the ram.
